NCT03499236
The objective of the RELIEVE-HF study is to provide reasonable assurance of safety and effectiveness of the V-Wave Interatrial Shunt System by improving meaningful clinical outcomes in patients with New York Heart Association (NYHA) functional Class II, Class III, or ambulatory Class IV heart failure (HF), irrespective of left ventricular ejection fraction, who at baseline are treated with guideline-directed drug and device therapies.
NCT03387813
The GUIDE-HF IDE clinical trial is intended to demonstrate the effectiveness of the CardioMEMS™ HF System in an expanded patient population including heart failure (HF) patients outside of the present indication, but at risk for future HF events or mortality.
NCT05882045
The main purpose of this study is to evaluate the efficacy and safety of retatrutide once weekly in participants with obesity and established cardiovascular disease (CVD). The study will last about 113 weeks.
NCT05428384
The investigation will enroll subjects who have been previously implanted with the CardioMEMS™ Pulmonary Artery Sensor. This clinical investigation is twofold; in the first phase (development phase) data collected will be used to complete development of an algorithm that can estimate cardiac output from CardioMEMS™ Heart Failure (HF) System readings. The second phase (validation phase) of this clinical investigation is intended to compare the Cardiac Output estimate from CardioMEMS HF System to Cardiac Output estimates from Cardiac Magnetic Resonance Imaging (reference standard).
NCT06906393
The purpose of this study is to investigate the chronic effects (i.e., 8 weeks, 3 times per week) of training at 50% and 75% of maximal power with 4-s sprint interval training on physiological adaptations. We previously examined the effect of training with an all-out intensity (i.e., 100% of maximal power) and reported increases in cardiorespiratory fitness. Now, we propose to examine the effects of a lower exercise intensity domains on cardiovascular fitness and its ability to stimulate the cardiorespiratory system. We hypothesize that training at 50% and 75% of maximal power will improve cardiorespiratory fitness similar to our previous findings while reducing the rate of perceived exertion during the exercise session. It is anticipated that the group engaged in training at 75% of maximal power will experience greater improvements in comparison to the group training at 50%.
NCT04600791
The purpose of this clinical investigation is to develop valid scientific evidence for the safety and effectiveness of the Barostim System delivered by the BATwire Implant Kit (BATwire Kit) in subjects with heart failure. Subjects may be enrolled if they meet the FDA approved PMA indication for use for the Barostim NEO or Barostim NEO2 device: Subjects who remain symptomatic despite treatment with guideline-directed medical therapy, are NYHA Class III or Class II (who had a recent history of Class III), have a left ventricular ejection fraction ≤ 35%, a NT-proBNP \< 1600 pg/ml and excludes patients indicated for Cardiac Resynchronization Therapy (CRT) according to AHA/ACC/ESC guidelines.
NCT03016754
This study is designed as a multi-center prospective observational study of newly diagnosed Heart Failure (HF) patients to test the hypothesis that additional Ejection Fraction (EF) recovery occurs between 90 and 180 days as Guideline Directed Medical Therapy (GDMT) is achieved. Although the study doesn't start until day 90, all eligible, consenting patients will be entered into a registry at the start of wearable cardioverter defibrillator (WCD) use. The pre-study registry will allow us to collect early (90 day) outcomes and data in those patients who are likely to be eligible for the study at day 90, or are eligible, but refuse the study at day 90.
NCT02235545
The purpose of this post approval study is to characterize the chronic performance of the SJM Optisure family of HV leads in patients.
NCT03153111
This is a study to evaluate whether macitentan is an effective and safe treatment for patients with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease. The primary objective is to evaluate whether macitentan 10 mg reduces N-terminal pro-brain natriuretic peptide (NT-pro-BNP) as compared to placebo in these patients.
NCT05100836
A multi-center, prospective \& retrospective, observational single-arm study of the clinical outcomes up to one year collected from electronic health records of patients which have undergone standard of care implantation of Impella 5.5, regardless of clinical situation or indication. All patients will be enrolled via an IRB-approved Waiver of Informed Consent and HIPAA Authorization. All patients who were supported retrospectively (prior to site IRB approval) with Impella 5.5 at the investigative site will be entered into the SURPASS registry and specified as the retrospective cohort.
NCT04847557
The main purpose of this study is to assess the efficacy and safety of Tirzepatide (LY3298176) in participants with heart failure with preserved ejection fraction and obesity.
NCT02922036
This study is a prospective, multi-center, pivotal trial to study the safety and efficacy of the WiSE-CRT System for Cardiac Re-synchronization Therapy.
NCT03089398
The purpose of the study is to learn which treatment option is better for patients who have multi-vessel coronary artery disease (blockages in more than one vessel supplying blood to the heart muscle). The treatment options this study will compare are: (1) Hybrid Coronary Revascularization \[HCR\] (a combination of surgery and catheter procedures to open up clogged heart arteries) and (2) Percutaneous Coronary Intervention \[PCI\] (catheter procedures alone to open up clogged heart arteries). There are no new or "experimental" procedures being tested in this study: both HCR and PCI are well-established procedures and are regularly performed in patients who have coronary artery disease. But, the FDA has not approved the drug-eluting stents used in PCI for all types of coronary artery disease. We have received an Investigational Device Exemption from the FDA to use the drug-eluting stents in this trial in the same way that they are used in clinical practice. The study being proposed here will use rigorous scientific methods and should result in a very high level of certainty about which procedure is best for patients with coronary artery disease.
NCT04591392
Evaluation of the safety and efficacy of the reSept ASD Occluder to treat patients with clinically significant secundum atrial septal defect
NCT03153137
The primary objective is to assess the effect of macitentan 10 mg as compared to placebo on exercise capacity through cardiopulmonary exercise testing.
NCT06062329
Evaluation of the Safety and Efficacy of the Symphony Thrombectomy System in the Treatment of Pulmonary Embolism
NCT04141605
The primary objective of this study is to collect real-world clinical performance data to assess the clinical outcomes of patients receiving heart transplants using donor hearts transported via the SherpaPak CTS System. These results will be compared to outcomes of retrospective patients whose hearts were transported with the previous standard method.
NCT04573660
The AV-MDR is a prospective, non-randomized, open-label, multi-center registry. The purpose of the AV-MDR study is to proactively collect and evaluate clinical data on the usage of the devices in scope within their intended use with the aim of confirming safety and performance throughout their expected lifetime, ensuring the continued acceptability of identified risks, detecting emerging risks on the basis of factual evidence, ensuring the continued acceptability of the benefit-risk ratio, and identifying possible systematic misuse or off-label usage such that the intended use can be verified as appropriate.
NCT06445608
This purpose of this trial is to demonstrate 30 day safety and effectiveness outcomes of the KARDION CORY P4 System in subjects who require hemodynamic support during a high-risk PCI procedure.
NCT00853632
The purpose of the study is to demonstrate the long term safety and effectiveness of the Carpentier-Edwards® PERIMOUNT Magna Mitral Valves in patients undergoing mitral valve replacement with or without concomitant procedures requiring cardiopulmonary bypass.
